This document discusses research design considerations for internet-mediated research (IMR). It addresses tools and procedures for quantitative and qualitative IMR, including surveys, experiments, interviews and observation. Key issues include balancing control, validity and accessibility. Careful attention to sampling frames, representation of populations, informed consent and anonymity is important. Further research is needed to validate IMR methods and better understand online populations and interaction effects. Overall, web-based approaches are preferable when control and functionality is required, though simpler methods may still have value depending on research goals.
